From: Pan Bian <bianpan2016@xxxxxxx>
commit 29d28f2b8d3736ac61c28ef7e20fda63795b74d9 upstream.
The member hba->pcidev may be used after its reference is dropped. Move the
put function to where it is never used to avoid potential use after free
issues.
Fixes: a77171806515 ("[SCSI] bnx2i: Removed the reference to the netdev->base_addr")
